  • Patent number: 12278345
    Abstract: An arrangement for pressure monitoring within a battery housing of a battery system. The arrangement includes a first power supply path and a pressure measuring. The pressure measuring unit is electrically connected to the first power supply path. The arrangement also includes a pressure-sensitive mechanical switching unit arranged within the battery housing and electrically connected, in series with the pressure measuring unit, to the first power supply path. The switching unit switches to an electrically conductive switching state when the pressure within the battery housing exceeds a predefined pressure threshold and establishes a supply of power to the pressure measuring unit via the first power supply path, and switches to an electrically blocking switching state when the pressure within the battery housing falls below the pressure threshold and interrupts the supply of power to the pressure measuring unit via the first power supply path.

  • Patent number: 12126063
    Abstract: Systems and methods are provided for integrating a chemical looping combustion system with molten carbonate fuel cells to provide improved operation of the molten carbonate fuel cells when using the exhaust from a gas turbine or other electrical power generation device as the CO2 source for the MCFC cathodes. This integration can be accomplished by using metal oxide in the chemical looping combustion system to oxidize the anode output flow from the MCFCs. This can reduce or minimize the number of separations that need to be performed in order to process the concentrated CO2 present within the anode exhaust. By reducing, minimizing, or eliminating the CO and H2 in the anode exhaust, the need to perform more costly separations (such as cryogenic separation or amine washing) to obtain a high purity CO2 product stream can be reduced or minimized. Optionally, the cathode exhaust from the molten carbonate fuel cells can be used as an oxygen-containing stream for regeneration of the metal oxide.
